To try to better understand humans' speech impairment after having a few too many, scientists let some birds drink the fowl equivalent of jungle juice to answer one question: Would it affect their vocals?
After feeding the finches juice with 6% alcohol in it, the birds' songs got a little wonky.
With their blood alcohol levels ranging from .05% to .08%, the finches appeared to be acting normal — that is, until they opened their beaks.
